Obelisk has only ever shipped one line of products - the SC1 and DCR1 chip, both of which were on the same reticle. Foundry based delays hit both the same way because… they are on the same wafer. We made up for it by putting forward a compensation policy which was completely fair - we gave our users credits equivalent to the revenue that they would have received from mining had their machines arrived on time. If any other user besides papacabeza feels that this compensation policy is not completely fair, I would love to hear about it.
Certain things are outside of our control. For example, TSMC has occasionally experienced delays due to things like tsunamis. If that were to happen, Obelisk would be unable to avoid missing a shipping date, because as a startup we don’t have the capital to source our chips from two different manufacturers, and we also don’t have the establishment to buy insurance.
Innosilicon also doesn’t have this type of protection, and in those events they would not be able to follow through on their guaranteed refund. For example, Innosilicon offered their customers ROI protection for a while on orders of T2 units. To the best of my knowledge, these units never did ROI, and also Innosilicon never paid out on the insurance they gave their customers.
In short: Innosilicon is making guarantees that they wouldn’t be able to follow through on, and they have done this in the past, and Obelisk is not willing to do that.
If we were a larger company that could afford to write off $20 million because TSMC got hit by a natural disaster and delivered chips 3 months late, we would give our users guarantees or insurance. We can’t do that though, therefore we can’t make promises that way.
